Review for Ameristar Casino - St. Charles Review For Pearl's Oyster Bar Google User Apr 26 '18 at 4:01 Here working the registration for a state association's conference. Room is very nice but far away from conference center part of the building. Staff at hotel and conference center are great! Facility very nice for a conference of our association's size except for long walks everywhere. The distance between meeting rooms and hotel rooms was difficult for some of our older members. Really enjoyed the service at the three different restaurants I've eaten at but the serving sizes were very skimpy at the steakhouse for the price. View full site to comment or like
